JOSEPH H. PILKINGTON, OF WATERBURY, CONNECTICUT.

SPRING-SLIDE.

Application filed April 10, 1914.

To all whom it may concern Be it known that i, JOSEPH H. PILKING- TON,citizen of the United States, and resident of Waterbury, in the countyof New Haven and State of Connecticut, have invented certain new anduseful improvements in Spring-Slides, of which the following is aspecification.

My invention relates to new and useful improvements in spring slides forsuspender webbing such as are used for attachment to one end portion ofa piece of webbing when employed to form part of a suspender or hosesupporter and is used for adjusting the length of the supporter.

The purpose of the invention is to provide an improved form of springslide which can be made entirely of sheet metal and constructed so as toform a simple and compact structure, without levers or hinged parts; todesign it so that it will normally tend to hold the webbing in a clampedor engaged position, but which can be conveniently pressed and operatedto free the webbing in a manner to allow it to be slipped backward andforward through the slide, further to form a spring slide to which thewebbing may be so attached as to cover the back of the slide and formwhat is commonly known as a rustless back slide and finally to form aslide which may be constructed of two parts of sheet metal each formedin such a way as to produce a comparatively small amount of scrap andwhich can be stamped and bent into form by light tools in a simple andinexpensive way.

With the above objects in view the invention further resides andconsists in the novel features of construction shown upon theaccompanying sheet of drawings forming a part of this specification,upon which similar characters of reference denote like or correspondingparts throughout the several figures and of which Figure 1 shows a frontperspective View of my improved form of slide as it appears attached toa piece of webbing as in use. Fig. 2 is a plan View of a sheet metalblank from which the front member of the slide is formed. Fig. 3 is adetached rear perspective view of the front or operative member of theslide. Fig. 4: is a plan view of a blank from which the rear or framemember of the slide is formed. Fig. 5 shows a detached front perspectiveview of the said frame member of the slide. Fig. 6 shows a centralvertical sectional view of the slide Specification of Letters Patent.

and attached web as shown in Fig. 1. Fig. 7 shows a horizontal crosssection through slide and web as seen on line 77 of Fig. 1. Fig. 8 showsa central vertical sectional view of the slide and web and is like Fig.6, except that the slide is shown compressed and the web in a releasedposition to permit it to be adjusted. Fig. 9 is a horizontal crosssection somewhat like F ig. 7 though in a released position to agreewith Fig. 8 and Fig. 10 shows a modified form or shape of blank formaking the operating member of my slide.

As before stated this slide is formed of two sheet metal parts each ofwhich are designed to be stamped out of sheet metal and then bent toform the particular shapes and constructions required. In Figs. 2 and 4.l have shown one of each of these blanks as they appear after being cutout from the sheet and Figs. 3 and 5 show the same blanks after theyhave been bent into shape and ready for assembling. The assembling ofthe two parts of the slide are completed by the connection and threadingof the webbing in the manner illustrated in Figs. 1, 6 and 8 as will belater further described.

The part shown in Fig. 5 and which is formed from the blank shown inFig. 4 is what I have designated as the frame member A, while the partshown in Fig. 3 formed from the blank in Fig. 2 will be designated asthe operating member B. The frame member as shown is formed of a singlerectangular shaped piece of sheet metal having an H shaped opening inits central portion. This special shaped opening forms upper and lowercross bands 10 and 11 and the inwardly disposed spring tongues 1212. Theend portions 1313 of the blank are then folded around back and inward soas to aline with each other to form the back to which the end 14 of thewebbing 15 is attached. It will thus be seen that when the said frame isbent into the shape described there will be formed an upper cludes afront plate 19 and one or more extended lips 20 which are bowed upwardand over the upper band 16 of the frame and has its free end portion orportions 21 disposed against the center portion of the webbing so as tobe engaged by the webbing and thus pressed outward away from the framemember. The free end portions 22-22 of the operating piece are foldedrearward and inward in almement with each other to form a loop 23, butwhich in practice bear against the spring ends 12 of the frame memberwhen the parts are assembled in the manner illustrated. This loop of theoperating member thus is arranged between the two loops of the framemember and register therewith so that the running portion of the webbingwhen threaded through the two parts of the slide will pass through notonly the two loops of the back, but also the one loop of the frontarranged between the two first mentioned loops. The pair of spring endson the frame member A tend to force and hold the operating member 13outward and thus bind that portion of the webbing which happens to liein the loop 23 of said member, between the edges 2l2 l of the two loops16 and 17 of the frame and the edges 25 of the single loop 22 of theoperating member. This tension or grip may readily be released bypressing a finger or thumb against the front plate of the operatingmember at the point designated by Press here in Fig. 1 which obviouslytends to force the spring ends down fiat and close thus bringing theloop 23 of the operating member into true alinement with the loops 16and 17 of the back thereby leaving them free to be slipped backward andforward upon the webbing. The moment the pressure is released from theoperating member the springs of the parts promptly tend to press thewebbing out again and bind it against the respective edges in the mannerpreviously described. The ends 22 of the part B, forming the loop 23,may be made to form springs or not as preferred. 1n practice I find thatthe spring end 12 when properly formed is suilicient to cause thewebbing to be grasped in the manner required.

It will be noted from the foregoing that as the running portion of theweb is tightened it bears against the end 21 of the lip 20 in a way toforce it outward and thus throwing out the upper edge portion 25 of theloop in a way to more firmly bind and hold the webbing, thus insuring atighter grip of the webbing with any additional tensile strain upon thesame.

Having thus described my invention what I claim and desire to secure byLetters Patent is 1. A spring slide for Suspender webbing Copies of thispatent may be obtained for five cents each, by addressing the comprisingtwo sheet metal members, one a frame-member including a pair of alinedloops through which the webbing is adapted to be threaded and a springintermediate of said loops, and the other an operating member alsoformed of sheet metal and likewise forming a loop that is situatedbetween the before mentioned loops and adapted to bear against thespring of the frame, the said loop of the operating-member beingdesigned to register with the loops of the frame.

2. A spring slide for suspender webbing of the class described, the samecomprising a frame-member and an operating member the former including apair of loops through which the webbing is adapted to be'threaded'and apair of springs intermediate of said loops, the operating-memberincluding a loop that is arranged between the loops of the frame anddesigned to bear against the springs of the frame, the said loop beingnormally held out of alinement, but adapted to be pressed'so as toregister with the loops of the frame in a manner to allow a piece ofwebbing to be freely drawn therethrough.

3. A spring slide for suspender webbing comprising two sheet metalmembers, one a frame-member including a back for the attachment of apiece of Webbing, a pair of alined loops disposed forward of the backand through which the webbing is adapted to be threaded and a springintermediate of said loops, and the other an operating-member includinga loop in its rear side that is situated between the before mentionedloops and adapted to bear against the spring of the frame, the said loopof the operatingmember being designed to register with the loops of theframe.

4. A spring slide for suspender webbing of the class described, the samecomprising a frame member and an operating member which the Webbing isadapted to be tnreaded and a pair of springs intermediate of said loops,the operating-member including a loop that is arranged between the loopsof the frame, and designed to bear against the springmember of theframe, an integral lip extended to engage a web, the said loop beingnormally held out of alinement, but adapted to be pressed so as toregister with the loops of the frame in a manner to allow a piece ofwebbing to be freely drawn therethrough.
